Clay and Quartz!
Silicon
The most abundant metal in the earth crust is aluminium.
oxygen 46.6%
Sulfur is the 16th most abundant element in Earth's crust, with an average concentration of about 0.03%. It is found in various minerals and ores, as well as in its elemental form near volcanic areas and hydrothermal vents.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Feldspar is the most abundant group of rock-forming minerals in the Earth's crust. It makes up about 60% of the Earth's crust and comes in different varieties such as orthoclase, plagioclase, and microcline. Feldspar is commonly found in igneous and metamorphic rocks.

Quartz is the most abundant single mineral. Feldspars are, as a group, the most abundant minerals. Quartz and feldspars are classified as silicate minerals, the classification of mineral with the most abundance in the Earth's crust.
silicates
Silicate minerals are the most abundant in Earth's crust and mantle because silicon and oxygen, the main components of silicate minerals, are the most abundant elements in the Earth's crust. This abundance of silicon and oxygen leads to the formation of silicate minerals through various geological processes, making them the most common type of minerals found in the Earth's crust and mantle.
